Login-walled surface
An AI surface that requires a signed-in account before it will answer: the Claude consumer app, Meta AI, DeepSeek, Amazon Rufus, Grok, and the Gemini web app. Anonymous proxy scraping structurally cannot reach them — there is no session to borrow. Reaching a login-walled surface takes either the vendor’s official API (a surrogate for the UI) or a real authenticated browser session.
In AI Search API
Claude is live today via the official model API, labeled api_surrogate — the honest interim. The authenticated account pool that captures login-walled consumer UIs is phase-2 roadmap: Meta AI, DeepSeek, Amazon Rufus and Grok are not yet valid surfaces values, and requesting them is rejected outright rather than mocked.
